Basically, you sign up on the website -- you can create an account with your email or with peeringdb or a thoughtwave account, set up a private ASN and it spits out a router config that you can use to start blackholing routes. I have been using it for months now on my edge router (AS54380) and it has cut SSH attacks down drastically.
It doesn't do volumetric protection against DDoS, but it will give you protection against brute force attacks. It ingest spamhaus, a bunch of other feeds as well as fail2ban from participants and also our own attack intelligence.
It's $59/month after the two week trial, and you can cancel at any time. I have a support ticket system. Would love to get some feedback.
